Description
Overview
The Dwyer Series 2000 Magnehelic is a low differential pressure gauge featuring a simple, frictionless movement that quickly indicates air or noncorrosive gas pressures in positive, negative (vacuum), or differential configurations. The rugged design resists shock, vibration, and over-pressures while maintaining weatherproof IP67 protection, making it ideal for HVAC systems, cleanrooms, and applications where no electrical power is available.
Key Features
- Frictionless Magnehelic movement with jeweled, shock-resistant bearings for accurate, stable readings
- Accurate within 1% of full scale; optional high-accuracy (HA) option provides 1% accuracy with mirrored scale and 6-point calibration certificate
- Patented quick-response design provides immediate reaction to pressure changes
- Rugged die-cast aluminum case with iridite dip coating for 168-hour salt spray corrosion resistance
- Clear, undistorted plastic face with precision litho-printed scale for easy viewing from distance
- Silicone rubber diaphragm with integrated O-ring seal for reliable pressure integrity
- Overpressure protection with blowout plug relief valve (standard on models below 180 in. W.C.)
- Zero adjustment accessible without removing cover
- Flush or surface mounting options with bezel flange
- No electrical power required for operation
Applications
- Filter and air flow monitoring in HVAC systems
- Blower and fan pressure indication
- Duct, room, and building pressure monitoring
- Cleanroom positive pressure indication
- Air velocity measurement with Dwyer Pitot tube
- Isolation and hospital environments
